Related top topics Automobile Did you know ... key relevance is a locksmithing term that refers to the measurable difference between an original key and a copy made of that key? From Wikipedia, the free encyclopedia A cut key A key is an instrument that is used to operate a lock . A typical key consists of two parts: the blade, which slides into the keyway of the lock and distinguishes between different keys, and the bow, which is left protruding so that torque can be applied by the user. The blade is usually intended to operate one specific lock or a small number of locks which are keyed alike. Keys provide an inexpensive, though imperfect , method of authentication for access to properties like buildings and vehicles. As such, keys are an essential feature of modern living in the developed world, and are common around the globe.

It is common for people to carry the set of keys they need for their daily activities around with them, often linked by a keyring adorned by key fobs and known as a keychain. Contents Main article: Yale key A house key is the most common sort of key. There are two main forms. The older form is for lever locks, where a pack of flat levers (typically between two and five) are raised to different heights by the key whereupon the slots or gates of the levers line up and permit a bolt to move back and forth, opening or closing the lock. The teeth or bittings of the key have flat tops rather than being pointed. Lever lock keys tend to be bigger and less convenient for carrying, although lever locks tend to be more secure. These are still common in many European countries. The more recent form is that for a pin tumbler cylinder lock . When held upright as if to open a door, a series of grooves on either side of the key (the key's profile) limits the type of lock cylinder the key can slide into.

As the key slides into the lock, a series of pointed teeth and notches allow pins to move up and down until those pins are in line with the shear line of the cylinder, allowing that cylinder to rotate freely inside the lock and the lock to open. These are predominate in the United States of America. Car key Ignition switch between the seats (2005 Saab 9-5 ). Car keys. A car key or an automobile key is a key used to open and/or start an automobile, and is identified with the logo of the car company at the head. Modern key designs are usually symmetrical, and some use grooves on both sides, rather than a cut edge, to actuate the lock. It has multiple uses for the automobile with which it was sold. A car key can open the doors, as well as start the ignition , open the glove compartment and also open the trunk (boot) of the car. Some cars come with an additional key known as a valet key that starts the ignition and opens the drivers side door but prevents the valet from gaining access to valuables that are located in the trunk or the glove box.

Some valet keys, particularly those to high-performance vehicles, go so far as to restrict the engine's power output to prevent joyriding . [1] Recently, features such as coded immobilizers have been implemented in newer vehicles. More sophisticated systems make ignition dependent on electronic devices, rather than the mechanical keyswitch. Car key in ignition. Switchblade key from a 2005 Land Rover LR3. Ignition switches/locks are combined with security locking of the steering column (in many modern vehicles) or the gear lever (such as in Saab Automobile vehicles). In the latter, the switch is between the seats, preventing damage to the driver's knee in the event of a collision. Keyless entry systems , which use either a door-mounted keypad or a remote control in place of a car key, are becoming a standard feature on many new cars. Some of them are handsfree . Some high tech automotive keys are billed as theft deterrents. Mercedes-Benz uses a key that, rather than have a cut metal piece to start the car, uses an encoded infrared beam that communicates with the car's computer. If the codes match, the car can be started.

These keys can be expensive to replace, if lost, and can cost up to US$400. Some car manufacturers like Land Rover and Volkswagen use a 'switchblade' key where the key is spring-loaded out of the fob when a button is pressed. This eliminates the need for a separate key fob. This type of key has also been known to be confiscated by airport security officials. [2] A switchblade key is basically no different than any other car key around. The only difference is its appearance. The switchblade key is designed to fold away inside the fob when it is not being used. To release the key from the fob you simply push a button on the side of your fob that triggers the keys release. Switchblade keys have become very popular recently because of their smart compact look. Because switchblade keys are only developed for new car models they are usually equipped with a programmed transponder chip. Master key A master key is intended to open a set of several locks. Usually, there is nothing special about the key itself, but rather the locks into which it will fit. These locks also have keys which are specific to each one (the change key) and cannot open any of the others in the set.

Locks which have master keys have a second set of the mechanism used to open them which is identical to all of the others in the set of locks. For example, master keyed pin tumbler locks will have two shear points at each pin position, one for the change key and one for the master key. A far more secure (and more expensive) system has two cylinders in each lock, one for the change key and one for the master key. Larger organizations, with more complex "grandmaster key" systems, may have several masterkey systems where the top level grandmaster key works in all of the locks in the system. A practical attack exists to create a working master key for an entire system given only access to a single master-keyed lock, its associated change key, a supply of appropriate key blanks, and the ability to cut new keys. This is described in Cryptology and Physical Security: Rights Amplification in Master-Keyed Mechanical Locks Locksmiths may also determine cuts for a replacement master key, when given several different key examples from a given system. Control key A control key is a special key used in removable core locking systems.

The control key enables a user with very little skill to remove from the cylinder, quickly and easily, a core with a specific combination and replace it with a core with a different combination. In Small Format Interchangeable Cores (SFIC), similar to those developed by Frank Best of the Best Lock Corporation , the key operates a separate shear line, located above the operating key shear line. In Large Format Removable Cores (LFRC), the key may operate a separate shear line or the key may work like a master key along the operating shear line and also contact a separate locking pin that holds the core in the cylinder. SFIC's are interchangeable from one brand to another, while LFRC's are not. Transponder key Transponder keys may also be called “chip keys”. Transponder keys are automotive ignition keys with signal-emitting circuits built inside. When the key is turned in the ignition cylinder, the car's computer transmits a radio signal to the transponder circuit. The circuit has no battery; it is energized by the radio signal itself. The circuit typically has a computer chip which is programmed to respond by sending a coded signal back to the car's computer.

If the circuit does not respond or if the code is incorrect, the engine will not start. Many cars immobilize if the wrong key is used by intruders. Chip Keys successfully protect cars from theft in two ways: forcing the ignition cylinder won't start the car, and the keys are difficult to duplicate. This is why chip keys are popular in modern cars and help decrease car theft. Many people who have transponder keys are not aware of the fact because the circuit is hidden inside the plastic head of the key. On the other hand, General Motors produced what are known as VATS keys (Vehicle Anti-Theft System) during the 1990s which are often erroneously believed to be transponders but actually use a simple resistor which is visible in the blade of the key. If the value of the resistor is wrong, or the key is a normal key without a resistor, the circuit of the car's electrical system will not allow the engine to be started. Double-sided key SentrySafe four-sided key A double-sided key is very similar to a house or car key with the exception that it has two sets of teeth, an upper level standard set of teeth and a lower, less defined set of teeth beside it.

This makes the double-sided key's profile and its corresponding lock look very similar to a standard key while making the attempt to pick the lock more difficult. Four-sided key (Also known a Cross Keys) As the name implies, this type of key has four sides, making it not only harder to duplicate and the lock harder to pick, but it is also physically more durable. Paracentric key A paracentric key is designed to open a paracentric lock. It is distinguishable by the contorted shape of its blade, which protrudes past the centre vertical line of the key barrel. Instead of the wards on the outer face of the lock simply protruding into the shape of the key along the spine, the wards protrude into the shape of the key along the entire width of the key, including along the length of the teeth. [3] Patented by the Yale lock company in 1898, paracentric cylinders are not exceptionally difficult to pick, but this requires some skill and know-how. Internal cut key An internal cut key has a rectangular blade with a wavy groove cut up the center of the face of blade, at constant depth.

Typically the key has an identical wavy groove on the back of the blade, making it symmetrical so it works no matter which way it is inserted. [4] Abloy key Main article: disc tumbler lock Abloy keys are cut from a metal half-cylinder. The cuts are made at different angles, so when the key is turned in the lock it rotates each disk a different amount. Nearly all the houses in Finland use Albloy keys. [5] [6] [7] Dimple key A dimple key has a rectangular blade with various cone-shaped dimples drilled into the face of the blade at various depths. Typically the lock has 2 rows of pins that match up with 2 rows of dimples. Typically the key has the same dimple pattern on the back of the blade, making it symmetrical so it works no matter which way it is inserted. [8] [9] Skeleton key Main article: skeleton key A skeleton key (or passkey) is a very simple design of key which usually has a cylindrical shaft (sometimes called a shank) and a single, minimal flat, rectangular tooth or bit.

Skeleton keys are also usually distinguished by their bow, or the part one would grasp when inserting the key, which can be either very plain or extremely ornate. A skeleton key is designed to circumvent the wards in warded locks . Warded locks and their keys provide minimal security and only a slight deterrent as any key with a shaft and tooth that has the same or smaller dimensions will open the lock. However, warded keys were designed to only fit a matching lock and the skeleton key would often fit many. Many other objects which can fit into the lock may also be able to open it. Due to its limited usefulness, this type of lock fell out of use after more complicated types became easier to manufacture. In modern usage, the term "skeleton key" is often misapplied to ordinary bit keys and barrel keys, rather than the correct definition: a key, usually with minimal features, which can open all or most of a type of badly designed lock. Bit keys and barrel keys can be newly-minted (and sold by restoration hardware companies) or antiques.

They were most popular in the late 1800s, although they continued to be used well into the 20th century and can still be found today in use, albeit in vintage homes and antique furniture. A bit key is distinguished from a barrel key in that a bit key usually has a solid shank, whereas a barrel shafted key can be made either by drilling out the shank from the bit end or by folding metal into a barrel shape when forging the key. Tubular key A tubular key A tubular key (sometimes referred to as a barrel key when describing a vintage or antique model) is one that is designed to open a tubular pin tumbler lock . It has a hollow, cylindrical shaft which is usually much shorter and has a larger diameter than most conventional keys. Antique or vintage-style barrel keys often closely resemble the more traditional skeleton key but are a more recent innovation in keymaking. In modern keys of this type, a number of grooves of varying length are built into the outer surface at the end of the shaft. These grooves are parallel to the shaft and allow the pins in the lock to slide to the end of the groove.

A small tab on the outer surface of the shaft prevents the pins in the lock from pushing the key out and works with the hollow center to guide the key as it is turned. The modern version of this type of key is harder to duplicate as it is less common and requires a different machine from regular keys. These keys are most often seen in home alarm systems, vending machines, and bicycle locks , in the United States. Zeiss key A Zeiss key (also known as a Cruciform key) is a cross between a house key and a tubular key. It has three sets of teeth at 90 degrees to each other with a flattened fourth side. Though this type of key is easy to duplicate, the extra sets of teeth deter lockpicking attempts. Do Not Duplicate key A keychain , a simple way to hold keys A Do Not Duplicate key (or DND key, for short) is one which has been stamped "do not duplicate" and/or "duplication prohibited" or similar by a locksmith or manufacturer as a passive deterrent to discourage a retail key cutting service from duplicating a key without authorization or without contacting the locksmith or manufacturer who originally cut the key.

More importantly, this is a key control system for the owner of the key, such as a maintenance person or security guard, to identify keys that should not be freely distributed or used without authorization. Though it is intended to prevent unauthorized key duplication, copying DND keys remains a common security problem. There is no direct legal implication in the US for someone who copies a key that is stamped do not duplicate (unless it is an owned key), but there are patent restrictions on some key designs (see "restricted keys"). The Associated Locksmiths of America calls DND keys "not effective security", and "deceptive because it provides a false sense of security." United States Code 18 USC Sec. 1704 deals with United States Post Office keys, and 18 USC Sec. 1386 deals with United States Department of Defense keys. Restricted key A restricted keyblank is a keyway and blank for which a manufacturer has set up a restricted level of sales and distribution. Restricted keys are often protected by patent, which prohibits other manufacturers from making unauthorized productions of the key blank. In many cases, customers must provide proof of ID before a locksmith will cut additional keys using restricted blanks.

These days, many restricted keys have special in-laid features, such as magnets, different types of metal, or even small computer chips to prevent duplication. Magnetic key Main article: keycard lock A keycard, while not actually considered a key, is a plastic card which stores a digital signature that is used with electronic access control locks. It is normally a flat, rectangular piece of plastic and may also serve as an ID card . There are several popular type of keycards in use and include the mechanical holecard , bar code , magnetic stripe , Wiegand wire embedded cards, smart card (embedded with a read/write electronic microchip ), and RFID proximity cards. The keycard is used by presenting it to a card reader; swiping or inserting of mag stripe cards, or in the case of RFID cards, merely being brought into close proximity to a sensor. Bar code technology is not a secure form of a key, as the bar code can be copied in a photocopier and often read by the optical reader. Magnetic stripe keycards are becoming increasingly easy to copy, but have the security advantage that one may change the stored key in a magnetic swipe card in case the current key may be compromised.

This immediate change of the "key" information can be applied to other media, but this media probably offers the least expensive option, and the most convenient to users and managers of systems that use this media. Example: If you own a car with this system, you can change your keys anytime you want. You can buy new media anywhere a gift card is sold. At least at this point in time, you could buy a gift card for a penny, then use that as the media for the keys to your car. If the system uses digital environmental data samples to create the "key" string, every car can have a set of keys that no one else has. If a card is stolen, or copied without authorization, the card can be remade, and the car security system can be synchronized with the new card, and no longer activationally responsive to the copy of the old card. This approach can empower the system controller (owner/individual or centralized administration of a business). Computerized authentication systems, such as key cards, raise privacy concerns, since they enable computer surveillance of each entry. Currently RFID cards and key fobs are becoming more and more popular due to its ease of use.

Many modern households have installed digital locks that make use of key cards, in combination with biometric fingerprint and keypad PIN options. The first keycard was the mechanical holecard type patented by Tor Sørnes , a concept he later developed into the magnetic stripe card key. History of locks and keys Main article: Lock (device) Wooden locks and keys were in use as early as 4,000 years ago in Egypt. [10] It is also said that key was invented by Theodore of Samos in the 6th century BC. In the United States, keys have been seen as a symbol of power since colonial times. When William Penn arrived in Delaware 1682, a very elaborate ceremony was carried out where he was given the key to the defense works. [11] Flat metal keys proliferated in the early 20th century, following the introduction of mechanical key duplicators, which allow easy duplication of such keys. Key duplication Mechanical Key duplicating machine invented in 1917, discussed in History, right. Video showing the process of cutting a key.

Key cutting (after cutting , the metalworking term for "shaping by removing material") is the primary method of key duplication: a flat key is fitted into a vise in a machine, with a blank attached to a parallel vise, and the original key is moved along a guide, while the blank is moved against a wheel, which cuts it. [12] After cutting, the new key is deburred: scrubbed with a metal brush to remove burrs , small pieces of metal remaining on the key, which, were they not removed, would be dangerously sharp and, further, foul locks. Different key cutting machines are more or less automated, using different milling or grinding equipment, and follow the design of early 20th century key duplicators. Key duplication is available in many retail hardware stores and of course as a service of the specialized locksmith, though the correct key blank may not be available. Certain keys are designed to be difficult to copy, for access control , such as Medeco , while others are simply stamped Do Not Duplicate to advise that access control is requested, but in the US, this disclaimer has no legal weight. Key Punching Rather than using a pattern grinder to remove metal, keys may also be duplicated with a punch machine.

The key to be duplicated is measured for the depth of each notch with a gauge and then placed into a device with a numeric slider. The slider is adjusted to match the corresponding measured depth and a lever is depressed which cuts the entire notch at once. As the lever is raised the key automatically advances to the next indexed position and the slider is adjusted appropriately to the next measured depth. This cycle is continued until the key is complete. Duplicating keys by this process is more labor intense and requires somewhat better trained personnel. However, keys made in this fashion have clean margins and the depth of the notches are not subject to wear induced changes encountered when heavily worn keys are duplicated using a pattern grinder. Keys may also be made in this fashion without an original as long as the depth of each notch and the type of key blank are known. This is particularly useful for institutions with a great number of locks for which they do not want to maintain a wide variety of archived copies.

History of key duplication A machine permitting rapid duplication of flat metal keys, which contributed to the proliferation of their use during the 20th century, may have been first invented in the United States in 1917 (image to the left): “ The key to be duplicated is placed in one vise and the blank key to be cut in a corresponding vise under the cutting disk. The vise carriage is then into such position by means of a lateral-feed clutch that the shoulders of both the pattern and blank keys just touch the guide disk and cutter respectively. The lateral-feed clutch on the top of the machine is then thrown, and the vertical feed rod released into action and power applied through the combination hand-crank power wheel on the right of the machine, until the cutter has passed over the entire length at the blank. A duplicate of the pattern key is obtained in about one minute. ” —"Man And His Machines", The World's Work XXXIII:6 April 1917 Key management Key management refers to systems for managing the possession, location and use of mechanical keys, or key cards within a building or organization, to aid in security and operations efficiency.

Symbols A key used as a symbol usually signifies a secure item, location, website, digital file or connection. Keys in Heraldry Coat of arms of the Vatican Keys appear in various symbols and coats of arms, the most well-known being that of the Vatican - derived from the story of Saint Peter , the first Pope , being given the Keys of Heaven.

It is common for people to carry the set of keys they need for their daily activities around with them, often linked by a keyring adorned by trinkets usually known as a keychain. Dimple - Lockwiki Dimple Dimple A DOM dimple lock. A dimple lock is a pin-tumbler -based lock design that uses flat side of the key blade as a bitting area. Cuts on the bitting area resemble dimples, hence the name. This contrasts traditional pin-tumblers that use the edge of the blade as the primary bitting area. Most dimple locks orient the keyway of the lock perpendicular to the pin stacks and allow the key to be inserted in any orientation. Dimple locks are used in a wide variety of applications, and may vary from low to high security. A dimple lock is not more secure when compared to traditional pin tumbler locks, but the untraditional nature of the key makes many dimple locks appear sophisticated. Some of the most notable dimple lock manufacturers are KABA , Mul-T-Lock , DOM , LIPS , and KESO .

Contents See Pin-tumbler (Principles of Operation) Traditional dimple locks are functionally equivalent to pin-tumblers; the plug may rotate when dimples in the key properly position a number of pin-tumbler stacks at the shear line . The only difference is the orientation of the keyway and the location and style of the bitting cuts on the key blade. More advanced dimple locks use various high-security features like key profiling, side pins , telescoping pins , and axial rotation . Additional passive and active locking mechanisms are also common, such as sidebars and moving elements within the key itself. The relationship between the keyway and the pins in a dimple lock limits the number of available depths for each pin (a function of the key thickness, pin design, and manufacturing tolerances). Where traditional pin-tumblers allow anywhere from six to twelve positions per pin, dimple locks generally allow two to six depths per pin. Regardless, modern dimple locks allow for pins positioned on all sides of the key, greatly increasing the number of pin positions available. This provides increasing key control and master keying capabilities when compared to traditional pin-tumblers.

Traditional pin-tumblers have problems with increasing the number of pins because the key must be extended to accomodate the extra pins. Past a certain point (generally seven or eight pins) traditional pin-tumbler keys become too long and have problems with bending and breaking. Vulnerabilities Key Cutting - Local Locksmith Key Cutting Key Cutting – Need Replacement Keys Cut? What types of keys can be cut? A Locksmith will be able to duplicate any set of keys and also cut keys to fit any type of lock. Keys for Cylinder Locks Patented Keys ( restrictions may apply ) Keys for Security Safes Zeiss key Types Of Key Cutting Services A Locksmith will be able to offer a variety of key cutting services should you need a replacement set of keys, most will be able to cut keys in store should they own a retail premises, or cut keys on site if they are emergency Locksmith. Keys Cut To Code Duplication of Keys should you need a spare set of keys What type of key can be duplicated? Depending on the type of key the Locksmith will be duplicating he/she will usually check over or hand finish the key to ensure no sharp edges.

This is usually done for various reasons: Most commonly finishing the new copy to ensure when the key is used in the lock it does not leave any scores or imperfections on the leavers/detainers inside the lock. If the levers or detainers were to get scored this could result in more than one lever/detainer lifting inside the lock in operation causing a potential lock out situation. The same applies to deburing cylinder type keys or any type of pin tumbler or wafer style lock as swarf (tiny fragments of metal) can get into the lock and cause issues with tolerances or reliability of that lock.

Only this Postcode Types of Locks – BosnianBill's LockLab Home LockLab University Types of Locks Types of Locks Warded Locks This is one of the oldest designs and, although it appears complex, the mechanism is very simple and easily defeated in under a minute. Inside the lock are simple chambers separated by thin metal walls, called wards. The keys have slots cut so the key can rotate freely, with the ward passing through the cut in the key.

In reality, the only security offered by these locks is people’s unfamiliarity with how simple the mechanism actually is. For most locks a thin pick can bypass all of the wards and rotate the actuator in only a few seconds. In addition, there are skeleton key sets for these locks that can be obtained for under $20. These locks offer the least amount of security of all lock designs. Wafer Locks Wafer locks are pretty simple mechanisms and are often used in dirty, high use environments because they are so tolerant of debris and contamination. You will find them on most cars and last for many years with little or no maintenance. Inside are small discs, or wafers that must be raised to a certain height to align and allow the lock to open. Tolerances are usually pretty loose and these are pretty easy to pick. However, there ARE high security versions that have additional grooves cut onto the wafer, called false gates. These are an anti-picking design and many modern cars use these along with a security side bar, that fits into a slot on the side of the wafers once they align properly. These types of locks are NOT easy to pick.

Pin Tumbler The pin tumbler is the lock we are most familiar with and it’s the most common type found. It has been in widespread use for almost 100 years and, depending on the manufacturer, can provide medium security. The security of this lock is guided by the number and type of pins in the lock and the number of depths on the key cuts. Most of locks that you’ll try to pick will be pin tumblers. Tubular Locks The tubular lock is another common type of lock that’s incorrectly considered “high security”. That assumption is wrong and is usually because of the lock’s obscurity. There are tools that allow these locks to be defeated in less than 1 minute. The ease with which it’s defeated is due to the low number of pins and the depth settings. The more complex and expensive of those is the Peterson Pro-1: (25) Review: Peterson Pro-1 Tubular Lock Pick . A cheaper and faster way to pick open most tubular locks is the SouthOrd Pick: (17) Beating the American Series 7260 7-Pin Tubular Lock . As time passes these are seen less and less.

There are high security versions of this style of lock, most notably the Van lock which is used on vending and gambling machines. Still, the Van is pickable as well, as seen in this video: (396) VAN High Security Cam Lock Picked w/Opening Tips . Dimple Locks This is a very common lock in Europe, but isn’t very common in North America. It was designed to prevent manipulation by putting the pins in a very narrow space, thus depriving the lock picker of working area. Unfortunately, there are specialized tools to pick these locks and lock pickers have become quite proficient at opening them quickly, usually in under 2 minutes. Several Chinese companies are selling a dimple lock bump tool: (430) Review: New Tool to Defeat Dimple Locks . Cross (Zeiss) Locks This is the cruciform, or cross lock. In Europe they sometimes call it the “Zeiss” lock, after the original inventor. It’s basically four different (sometimes only three) locks built upon a single key. Because of the compact keyway, the number of depths of cut for the key is reduced, making it a little easier to pick.

You can pick them manually: (133) Concept 15-Pin Cruciform Cross Cylinder SPP’d , by raking (253) How to Pick Cross (Zeiss) Locks , or using Cruciform Jiggler keys: (106) Review: Cross Tryout Keys . Interactive Dimple (Mul-T-Lock) This is a modern high security lock manufactured by Mul-T-Lock Corporation. There are a number of different models with increasing levels of picking difficulty. One of the easiest to pick is the G-Series: (146) Mul-T-Lock Garrison Lock (6-Pin) SPP’d . The Interactive model has a unique pin that cannot be “read” visually, instead custom forming only once it’s inside the lock. Still, they are possible to pick: (398) Mul-T-Lock Interactive Picked & Gutted + Opening Tips . The top of the line model is the MT-5+ and offers the highest level of security. I have not yet been able to pick one of these. Bi-Axial (Medeco) Medeco locks are some of the highest security locks available.

They are so secure that the Military used a pair of 6-pin Medeco-cored locks to secure nuclear weapon magazines. For conventional ammunition and weapons storage rooms, a single Medeco is enough. Still, it’s possible to pick them but they are, by far, the most difficult-to-pick locks I know of. Even on my best day my success rate is pretty low. Still: (174) Medeco 6-Pin Mortise Cylinder Picked Open & Gutted , and (164) Medeco BiAaxial Picked Open & Gutted . Still, it IS possible to occasionally get very, very lucky: (540) Rake Open Medeco Locks? YES! . Disc Detainers (Abloy) This is a disc detainer lock, one of the most secure and pick resistant locks made today. This simple (and cheap to manufacture) design contains discs that must be rotated to a precise angle (every 11-16 degrees is a possible gate cut). If a single disc is misaligned, the lock will not open. It contains no springs or other mechanism to provide feedback to the lock picker.

The Abloy brand disc detainer is the top of the line and offers the highest level of security of all locks. I have never been able to pick an Abloy disc detainer, nor do I know of anyone that can. If you want the ultimate high security lock, look no further than an Abloy. There are lesser quality copies of the Abloy design. These knock-offs are cheaper, contain fewer discs, are made from inferior materials, and don’t contain the anti-picking features. Obviously, they are MUCH easier to compromise.

The type of key that is being duplicated Depending on the type of key the locksmith will be duplicating he/she will usually check over or hand finish the key to ensure no sharp edges. This is usually done for various reasons: 1. Most commonly finishing the new copy to ensure when the key is used in the lock it does not leave any scores or imperfections on the leavers/detainers inside the lock, 2. If the levers or detainers were to get scored this could result in more than one lever/detainer lifting inside the lock in operation causing a potential lock out situation. 3. The same applies to deburing cylinder type keys or any type of pin tumbler or wafer style lock as swarf (tiny fragments of metal) can get into the lock and cause issues with tolerances or reliability of that lock. These are actions and practices a locksmith would take as they have a great understanding of what goes on inside the lock once the key is entered.
